** Thanks for contacting HCM with your health concern 1. Since high eosinophil count is not a disease but symptom of an underlying disease thus one has to consult a medicine/allergy or infectious disease specialist to exclude possibilities of eosinophilia like: i. allergic disorders; [asthma,hay fever,eczema,serum sickness] ii. parasitic infections: [hookworm,ascariasis,schistosomiasis,filariasis and tropical eosinophilia] iii. Drugs like aspirin,penicillin,iodides,sulphonamides,nitrofurantoin iv. any malignancy or collagen vascular disease 2. Your Doctor will conduct dermal sensitivity test(s) to establish the cause of allergy [if present] and then prescribe you a schedule of avoidance therapy and drug therapy for long term relief.
